Default/Allowed: ON or OFF
min
Minimum gap between Spot location and the weld plates.


Default/Allowed: 1.0 to 10.0
max
Maximum gap to be considered between Spot location and the weld plates. This value is added to filter some spotwelds which are too far from the model.
Default/Allowed: 10.0 to 100.0
Spot weld between min and max distance from the nearest flange is identified, perpendicular distance is checked.

Multi-Layer

do-check
Turn OFF or ON the check
Default/Allowed: ON or OFF
threshold
Maximum allowed spot weld layers.
Default/Allowed: 2 to 4
Spot welds that has layers more than threshold value are identified for reference. It is expected to have a notch to allow Spot gun.


hm-issue

do-check
Turn OFF or ON the check
Default/Allowed: ON or OFF
Spot welds that are far from the Sheet metal part by “tolerance” search are identified and Part missing issues are directly identified by HyperMesh.
Tol
realize-tolerance (tol)


Parallel-flanges

do-check
Turn OFF or ON the check
Default/Allowed: ON or OFF
angle
Maximum angle between two plates at spot location.


Default/Allowed: 2.0 to 15.0
max-gap

Default/Allowed: 1.0 to 5.0
Non-Parallel flanges are identified at Spot weld location, if the angle between two sheet metal parts is more than angle value and more than gap value are identified.


Incorrect-Location

do-check
Turn OFF or ON the check
Default/Allowed: ON or OFF
min-distance (min)
Minimum distance allowed from feature-line to the spot location.


Default/Allowed: 1.0 to 5.0
Issue is Identified, if the distance between Spot weld and the nearest feature edge is more than the tolerance value. The tolerance refers to Spot gun “radius+gap”.


Few-Connections

do-check
Turn OFF or ON the check
Default/Allowed: ON or OFF
Proximity (a)
Search tolerance for realizing spot weld on the flanges, it is global pitch.
Default/Allowed: 1.0 to 5.0 mm
pitch-spacing (b)

pitch-offset (c)
End offset distance on both side of the flange.
Default/Allowed: 5.0 to 8.0
pitch-edge-distance (d)
Offset distance from the edge of the flange.
Default/Allowed: 5.0 to 8.0
search tolerance (e)
Tolerance for searching Virtua connectors from existing connectors created from above parameter.
Default/Allowed: 30.0
hole-diameter (f)
Search tolerance for finding nearest Bolt holes to avoid finding the issue.


Default/Allowed: 4.0 to 40.0
Creating virtual spot (VS) welds with above parameter. For every virtual connector (VC) search nearest existing spot weld (blue) with “search tolerance” value, identify location (yellow), if blue spot weld not found.


Flange-gap

do-check
Turn OFF or ON the check
Default/Allowed: ON or OFF
limit
+/- ratio of shortest gap between flanges at connector to average component thickness value. It is also % of deviation.


Calculation : abs( D - d ) ≤ limit
Default/Allowed: 0.1 to 0.5 mm
This ratio of flange gap to average thickness of the component is compared with tolerance value. Issue is identified if the difference is same or less than the limit value.
Note: No Error will be reported if thickness does not exist or offset is not done.


Intersection

do-check
Turn OFF or ON the check
Default/Allowed: ON or OFF
spot-layers
Maximum number of layers considered for this check.


Default/Allowed: 2 to 3
Intersection on Spot realized FE data is found here or 2 layer to 3 layer or 3 layer to 4 layer conversion possible welds are identified.


Fillets

Fillet identification angle


do-check
Turn OFF or ON the check
Default/Allowed: ON or OFF
fillet-connelem-tol
Search tolerance for searching nearest fillet edges to the connector.


Default/Allowed: 10.0
If Spot welds location less than the fillet-connelem-tol distance from the nearest feature, line is identified here.


Reflect

do-check
Turn OFF or ON the check
Default/Allowed: ON or OFF

Reflecting plane for the model which the spot welds are reflected and checked again for realization.


Default/Allowed: zx
origin
Origin value. (for XY plane, origin is constant Z value)
Default/Allowed: 0 to 1000.0

Failed spot welds are reflected at reflect-plane and re-realized, if successful in realization, it is identified as issue.

Issues will be ignored if surface offset is not executed and another spotweld exist at reflected location.


surrounding

Default/Allowed: ON or OFF
spot-layers
Maximum number of layers considered for this check.


Default/Allowed: 2 to 3
Intersection on Spot realized FE data is found here or 2 layer to 3 layer or 3 layer to 4 layer conversion possible welds are identified.
